Researchers have developed EditPPT, a novel multi-agent framework designed to automate the editing of long presentation decks. This system reformulates slide editing as a constrained tool-selection problem, utilizing the native PowerPoint COM interface for localized, shape-level operations. EditPPT addresses common failures in existing LLM-based systems by narrowing the action space and employing dual-modal validation for instruction fidelity and visual quality. A new benchmark, DeckEdit-Bench, comprising 28 decks and 183 editing prompts, demonstrates EditPPT's high execution rate and strong performance across various deck lengths. AI
IMPACT This system could significantly improve the efficiency of content creation and editing for presentations, particularly for long and complex decks.
